First of all I want to start off by introducing myself. My name is Pat, Im 37 married with 2 kids. I love trucks and muscle cars. We currently own a 98.5 Dodge Ram 3500 Dually 2wd with a 24valve Cummins. Aftermarket BD Air intake, 4" exhaust and a Super Chip. Truck was purchased new out of Tampa Fl. and now resides here in Vancouver BC Canada. We are having a problem with the interior blower motor....It wont shut off. I have replaced the resistor, heater switch, and relay with no success. Has anyone come across this? Thanks in advance
